I could not be with someone who didn't want kids. It would be a deal breaker for me. They are such a huge, important part of my life. To be honest I cant stand being around other peoples kids for long periods of time, but my own? I can't imagine life without them.

Personally I feel that the topic of kids is such a huge life impacting one that if you can't agree on the subject, then it wouldn't be worth it in the long run. One of you may find later down the road that you regret having to make such a huge sacrifice by choosing one direction in life and not the other. But that's just my personal opinion. It really depends on how much you want to have a child in your life.
